Claims.

This invention pertains to improvements in wringer structures, having to do particularly with a novel manner of instantly releasing the pressure between the wringer rolls.

The main object of the invention is to provide a very simple means of bringing about the release of the upper wringer-roll in which a minimum of elements will be involved thus eliminating complications and producing a more positive release action.

Another object is to furnish in combination with a clutch mechanism a simple control arrangement directly engaged by the usual top closure-portion by which said clutch mechanism can more positively function.

Still another object is to employ the fewest number of parts in a clutch control arrangement in order that there will be less chance for wear between parts or misadjustment of said parts such as would lead to inaction at a critical moment. a

To the end that the. invention may be fully understood, the accompanying drawings are provided forming part hereof.

Figure 1 is a side elevation of a wringer constructed according to the present invention;

Figure 2 is an enlarged transverse sectional elevation of the structure of Figure 1 produced on line 22 of that figure;

Figure 3 is an elevation, also enlarged, of part of the wringer body as viewed from the left of Figure 1;

Figure 3 shows a cam in perspective;

Figure 4 is a longitudinal section of a gear box portion of the wringer structure, produced on the same scale as Figures 2 and 3;

Figure 5 is a transverse elevation of parts of a gear control structure produced on line 55 of Figure 4;

Figure 6 is a plan of parts shown in Figures 4 and 5 produced on line 6-6 of the last named figure;

Figure 7 is an end elevation of a portion of the wringer body as viewed at the right of Figure 1, parts being shown in section;

Figure 8 is a plan of a control mechanism shown in Figure '7 produced on line 88 of that figure, together with parts shown in Figure 6, and

Figure 9 is a reproduction of parts shown in Figure 8.

The invention forming the subject-of this application is somewhat along the lines of the invention of pending application of Albert R. Haag, Frank W. Werckle and Ross E. Locher, Wringers,

filed under date of November 4, 1937, Serial No. 172,819 but differs therefrom in that control means for the wringer-roll drive is directly infiuenced by the top closure portion of thewringer as a simplified structure for producing very positive results. 7

In the drawings hereof 1 denotes the wringer frame, 2 a top closure portion, and 3 and 4 a lower and an upper wringer roll respectively, the usual gear box being indicated at 5.

In the present instance the closure portion 2 is hinged to the frame I at one side thereof but, perhaps may be otherwise controlled.

The shafts of the wringer rolls 3, 4 have their bearings in blocks 3', 4' respectively, Figure 2, said blocks being slidable in guide ways 6 created between opposed walls 1, Figures land 2 in much the usual manner, the shaft 8 of the lower roll 3 extending into the gear box 5 and having slidable thereon but rotatable therewith a pair of gears 9, l 0 fixed relatively. v I

Any usual power shaft is indicated at H and carries a gear 12 within the gear box, either of the gears 9, ll] being adapted to separately mesh with the said gear I 2 in the well known way.

Suspended above the gears is a cam l3 mounted to rotate with a shaft portion l4 thereof.

Depending from the upper wall of the gear box, in this instance, is a bearing I5 within which the said cam I3 is rotatable. The cam as at present constructed is for the most part cylindrically formed in order to rotate in said bearing but is recessed at l6, Figures 3 4, 5 and 6.

At the bottom of the recess are three faces ll, l8, I9, the two latter, l8 and 19 each lying at an angle, in this instance" of substantially to the face H, the several faces otherwise substantially paralleling the axis of cam rotation. The shaft portion I4 is axially coincident with the wringer shaft 8, Figure 5, and beneath the cam is suspended a slide 20 by means of an extension 2 I' of the former which is eccentric to the saidshaft portion l4, said slide engaging in a groove 22 of the gears 9, l0, being slidable in said groove in a direction naturally paralleling the faces of said gears.

slidable in a bore 1' of that wall of the wringer frame I adjacent the gear case, and slidable also in an extension of the bearing I5 is a member or rod 23. One end of said rod-is adapted to abut any one of the faces of the cam l3, while in and near the other end at the said wall of the frame I the rod has a recess, preferably-a groove 24. A coil spring 23' encircles therod which is under compression between the named wall'of the frame I and a pin 23 for example, carried by said rod, by which the latter is normally urged in the direction of the cam I3.

As shown in Figures 7 and 8 the named wall of the frame I is provided with a bore 25 said bore opening into the bore 1 and also opening upon the top surface of the frame 6 whereon is received the top closure portion 2. Slidable in the bore 25 is a pin 26 and between the latter and the bore I is spring 21 and a ball 28, the latter adapted to either abut upon the rod 23 or to engage in the groove 24 thereof.

In either position of engagement of the ball,

the spring 21 is under compression and thereby the pin normally extends above the said top surface of the frame. Any conventional means may be employed to retain the pin within the said bore 25.

Clearly, upon closing the top portion 2 its under surface will engage and depress the pin 25 against the tension of the spring 21, while also placing pressure upon the upper roller 4 as now to be seen.

The said top portion includes in this particular instance, a flat spring 28', the ends of the springs being guided between ears 29 of said portion and resting upon cross pins 3|] carried by the latter, Figures 1, 2 and 3. The spring 28 is illustrated as secured to the top 2 by a conventional rivet passing through the spring at about the middle point of its length, but the exact manner of securement for the spring to the top cover does not comprise any part of the present invention. In Figure 2 the upper wringer-roll bearing 4' is shown as extending to a position to receive the end of the spring 28' thereon, said spring exerting pressure on the upper roll when the top portion is in abutment with the frametop.

Latching means is comprised, in thi case, in a shaft 3| journaled in the top portion and extending throughout the length thereof, each end of the rod having afiixed thereto a latch 3|, one of them including an upstanding handle portion 32, said latches adapted each to engage beneath a cam-part 33 of the frame I.

In referring to Figure 8 the face IQ of the cam 13 is shown in a position of unrest in dotted lines. That is to say, it is noted that the rod 23 due to the spring 23' is being urged toward said cam and rests against a part of a face thereof that lies in a position eccentric to the center of cam rotation. In such a position of the cam that member would be rotated toward the left until said rod comes into abutment with the face H as illustrated in continuous lines as the normal po- 'sition of the parts, the broken lines position being maintained by controlling the rod 23 by the pin 26 already described as will now be more fully set forth. When the top portion 2 i unlatched and therefore not depressing the pin 26 the rod 23 is free to shift lengthwise by and through hand act ation of the cam 13, the spring 23 upon the release of the cam however, carrying the latter to the position shown in Figures 4, 6 and 8 as before stated as the normal position of the said cam, and at the time the gears are in neutral.

Now, upon closing the top portion and latching it the pin 26 has been depressed forcing the ball 28 toward and upon th rod when the latter has the position shown in 'Figure 8. By turning the cam to bring about the meshing of either of the gears 9, 10 with the power-'drivengear 12 the slide 20, through the swing of the extension 2| of the cam in the direction chosen, and at the same time a cam face l8, l9, corresponding to the gear chosen, meets and shifts the rod 23 against the tension of its spring 23' with the result that the groove 24 is carried beneath and opposite the spring held ball 28 wherein the latter enters, Figure 10, its entry thus maintaining the engagement of the gears selected.

Instant release of the gears is accomplished by striking the latch handle 32 to disengage the latches 3 I from the cam 33 whereupon the spring 28' in the top portion 2 exerts itself to lift said portion releasing the top roll 4 and permitting the pin 26 to release pressure on the ball Within the groove 24. The spring 23 on the rod 23 is strong enough to force the ball from the groove the said rod acts upon the cam face upon which it has been resting to swing the cam and disengagethe gears.

The invention contemplates the use of any other convenient part of the wringer structure for depressing and releasing the pin 26. That is to say, the invention'is not confined to the employment of a part of the top portion 2 necessary for the purpose named.

Changes may be made in the structure such as may be considered to fall within the claims to follow.
